No sound when using sfplay and umenu

I’m attempting to create a music player that can be manipulated with the use of the Wii Remote. I’ve set up a umenu so that I have a list of sound flies ready and I have everything set up so that the sound can be played forwards and backwards by tilting the Remote right and left respectively and that A and B can play and stop the sound. The problem I am currently having is that I can’t hear any audio and no errors come up in the Max Window.

What would be the best method of fixing this issue? Or what other alternative methods are there? The Patcher is linked down below.

Thank you.
